Summary
Brief summary (as posted)
The current standard for recurrent, persistent or metastatic cisplatin-resistant ovarian cancer is palliative chemotherapy with either topotecan, liposomal doxorubicin or gemcitabine, however, the results need to be improved. Epigenetic aberrations play an important role in cancer progression by silencing growth regulatory genes and there is now evidence that inhibitors of DNA methylation and HDAC inhibition synergize the cytotoxicity of chemotherapy. Objective. To determine the superiority of epigenetic therapy with hydralazine and valproate plus topotecan over placebo plus topotecan upon progression-free survival. Hypothesis. Hydralazine and magnesium valproate associated to topotecan will increase progression-free survival from 6 to 9 months as compared with the same regimen of chemotherapy plus placebo.
